Sulfamethazine-13C6（Cat No.:S000517） is an isotopically labeled form of sulfamethazine, where six carbon atoms are replaced with carbon-13 (13C). Sulfamethazine is a sulfonamide antibiotic used to treat bacterial infections in animals. This isotopic modification enhances its traceability and stability, making it particularly useful for research in pharmacokinetics and metabolic studies. By using 13C labeling, scientists can more accurately track the drug’s absorption, distribution, metabolism, and excretion in the body.
